Abstract: Objective To explore the feasibility and evaluate the outcome of surgical treatment of tibial plateau fractures under arthroscopic guide.Methods From May of 2006 to Feb of 2007,eighteen cases of tibia plateau fractures underwent the procedures of surgical treatment under arthroscopic guide and help reduction.The patients were 32.5(20～54) years old at average,male in 8 cases,female in 10 cases.Six cases combined with meniscus lesion and 3 cases with medial collateral ligament injury.For Schatzker classification,the 18 cases were divided into type Ⅰ in 7 cases,type Ⅱ in 5 cases,type Ⅲ in 4 cases and type Ⅳ in 2 cases.Results Healed fractures were found at 3～8 months after operation in all 18 cases,and there were no infections,compartment syndromes or other complications.The average follow-up period was 12 months(9～18 months).According to the Sanders evaluation criterion,17 cases were in excellent and good conditions,and there were no traumatic arthritis,varus and valgus deformity in all cases.Conclusion Treatment of tibial plateau fractures under arthroscopic guide can avoid opening up the knee joint,it's less invasive and safe procedures make it possible to treat the combined injuries in the knee at the same time with rehabilitation easier.This treatment is especially effective to type Ⅰ～Ⅲ and some Ⅳ of Schatzker classification.
